Mustafa I
15th Sultan of the Ottoman Empire (1617–1618, 1622–1623)
Mustafa I (; Ottoman Turkish: مصطفى اول; Turkish: I. Mustafa; 1601 or 1602 – 20 January 1639) was twice the sultan of the Ottoman Empire from 22 November 1617 to 26 February 1618, and from 20 May 1622 to 10 September 1623. He was the son of sultan Mehmed III and Halime Sultan.
Early life
Mustafa was born in 1601 or 1602 in the Topkapi Palace. He was son of Sultan Mehmed III and Halime Sultan, an Abkhazian concubine.
Before 1603 it was customary for an Ottoman Sultan to have his brothers executed shortly after ascending the throne, (Mustafa's father Mehmed III had executed his nineteen half-brothers). But when the thirteen-year-old Ahmed I, Mustafa's older half-brother, was enthroned in 1603, he spared the life of Mustafa. Handan Sultan, mother of Ahmed I, was crucial to Mustafa's survival, as she convinced her son to spare his life, not believing him to be a threat due to him being considered mentally weak.
A factor in Mustafa's survival is the influence of Kösem Sultan (Ahmed's favorite consort), who may have wished to preempt the succession of Sultan Osman II, Ahmed's first-born son from another concubine. If Osman became Sultan, he would likely try to execute his half-brothers, the sons of Ahmed and Kösem. (This scenario later became a reality when Osman II executed his half-brother Mehmed, the oldest son of Ahmed and Kösem, in 1621.) Furthermore, when Ahmed ascended the throne, Mustafa was the only possible heir.
Begin with the source’s own compact description: “Mustafa I” is 15th Sultan of the Ottoman Empire (1617–1618, 1622–1623). The dossier treats that line as a proposition to test through Mustafa, 15th and Sultan, not as a finished interpretation.
Why this record matters
The phrase “15th Sultan of the Ottoman Empire (1617–1618, 1622–1623)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q174798. VIAF identifies the subject as 265348924. The Library of Congress control number is nr93002021. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1601, 1602, 1639 and 1617.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
